Experiment Research On Fully Optial Acquisiton In Laser Communication For Amry

In laser communication, acquisiton is the first step, and also a very important step.The purpose of acquistion is to be ready for the communication link by acquiring laser link of the other side. Acquisition relates whether the communication link can be built,so the research of acquistion is meaningful.The paper researches in acquistion of laser communication in amry field.lt proposes a new method in acquistion called fully optical acquistion.Compared with acquistion by GPS/INS navigation system, the new method has strong ability of anti-electromagnetic interference.The paper mainly anlyzed the technology of fully optical acquisiton and its strategy, and choosed key devices such as lase、CCD camera、filter and turn-table,then builds experiment platform. The paper designed control loop and circuit based on the need of fully optical acquistion.Based on the conditon of amry field, the paper designed long beam and big divergence angle of laser beam.In the end of the paper, the periment was done between the two platform, the distance of which is1kilometer.The results demostrated that the fully optical acquisition meets the quirement.
